Hi All, was at atuo electrians and we have a problem with putting a double fillment light bulb into the side lights on my 31, I wanted to acheive them as side lights and indecators, has anyone worked through this problem before? the double fillment bulbs with a equal pins at the base are too long in lenght and you cant put the glass lense on



thanks Mike



ps I dont care if I have to bring them in from the states if someone is willing to help

    You're having trouble physically making them fit? The first question would be, does the socket accept double contact bulbs, or is it a single-contact socket?



    Once you solve that, it is possible to go to a "small lamp" catalog to find the bayonet-style double-filament bulb whose height may permit it to fit in the confines of your enclosure.

    The problem isnt with the bannet fitting this has been change to a to contact fitting, its with the lenght of the bulb, ie

    most of the bulbs down under with a double filament is used for head lights

    where the size bulb that Iam looking for is more the size of a torch size bulb ie about 1/2' round and quite stumpy, if this makes sense

    thanks

    Mike, you will have to modify the reflector and fit a second bulb holder and bulb, at an anlge to the original one. If you want to use a doube filament bulb you will have to eliminate the bulb holder, fit the double filament bulb in the hole, and solder the wires directly to the back of the bulb with an insulator strip to make sure the wire doesn't contact the light frame at the back. There is just not enough length to use a proper bulb holder inthe small lights. another possibility is to use a festoon bulb for the indicator, but this again means modification. Sorry 'bout that chief!

    Geoff.

    So, a standard double filament brakelight bulb and socket are too tall to fit, eh?



    Let's see: are these cowl lights normally on whenever the headlights are, or are they only parking lights?



    Another question: does the car now have double-filament taillights, with one filament acting as the brake light and the other as the taillight at night? And if so, will you be wiring these through the turnsignal switch so that the brakelight filaments will then share their function with the turn signals? Or, will you simply attach a separate set of rear lights to serve as turn signals?



    Using the cowl lights as turnsignals only takes care of the "frontal" half of the equation...

    The standard is way to big, can only be 1 1/4 long by 3/4' round,

    we do have doulble fillment tail lights as have fitted model A after market ones that have 2 sets of bulbs, the lights would work as parkers and as indecators at the same time, I am having trouble with altering the reflectors as they are in 10 condition

    Well, you didn't answer my question about how you'd handle your taillights.



    So here's what I was driving at: if you have a car with separate add-on left and right signal lights in back, then you could purchase the type of turnsignal switch that works with cars only having a double-filament bulb in the taillight. (The switch routes the brakelight circuit through the switch).



    BUT you would turn the circuit around so that the "split circuit" (normally to the rear brake / turnsignal filament) now goes forward, to the cowl lights. So, each single filament cowl light now shares two functions: parking light AND turn signal. (The switch is fed its power from the cowl light, not from the brake light as is normal in this type of "shared function" switch.)



    Meanwhile, the wires from the switch which normally feed the FRONT left and right bulbs, now go to the REAR. Where they feed the separate left and right turnsignal lights.



    That is, IF you have added separate left and right rear turnsignal light fixtures.

    Thanks John, I understand, and will have a look at this and talk to my auto electrian about this, I woukd have thought I could have just brought a bulb, but like everything on the old girl nothings simple



    Its Labour weekend here and its a long weekend, I was pulling the car out of the auto electrians today but its going to pour down with rain (which seems to be they way each year)so I will wait to Tuesday as there is no glass in her yet and I want to show her off on the trailer, Iam having it fitted for a new set of feet, as we have to get a special off set foer the rear and thats about a 8 week delivery, once that is done of to the painters for a couple touch ups
